Geodelphia have begun a comprehensive measurement of gas leaks in the City of Philadelphia, funded by Sierra Club’s Southeastern PA Group.

To see what we’ve measured, you can find your address on this Google Map. Note that number on the map is for methane level that is calculated by subtracting the ambient methane level from the reading taken in the study, in parts per million (ppm). 

Concerned about a possible explosion near you? You should be! If you can, please fund a comprehensive study for our entire city. Then share this page with your neighbors.
